Asynchronous tasks in Django with Django Q: why not Celery?įun fact: Celery was created by a friend of mine. The Schedule associated with Person is deleted with (pk=self.schedule_id).delete(). delete ( ) # Delete the person super ( ).
save ( *args, **kwargs ) def delete (self, *args, **kwargs ) : # Delete the schedule DAILY, ) # Save the model with the schedule id IntegerField (default = 0 ) def save (self, *args, **kwargs ) : # Create the schedule First let's create the model in demo_app/models.py: Let's say that when a new Person instance is created we want to send out an email every day. This model has nothing to do with the Django user model and it's just for illustrating things out. To illustrate Django Q schedules we're going to create a new model named Person. A practical use case: sending an email when a new model instance is created If you don't need other brokers than Redis, django-rq might be a lightweight alternative to Django Q.

If you're new to Redis, it's an in-memory database, can be used as a cache and as a message broker.Ī message broker is more or less like a post office box: it takes messages, holds them in a queue, and folks from around the city can retrieve these messages later. I'm using Heroku here because you may want to deploy to production later, also because they offer the Redis add-on for free. In this section we'll prepare the Heroku project. Preparing the Heroku app and the Redis instance This is a nice alternative to bringing in task queues for simpler tasks, but I don't feel it's a reliable workaround for more intensive use cases. create_task (crunching_stuff ( ) ) return JsonResponse (json_payload ) Sleep ( 10 ) print ( "Woke up after 10 seconds!" ) async def index (request ) : From time import def crunching_stuff ( ) :
